Please help :( The mean incubation time for a type of fertilized egg kept at 100.9​°F is 20 days. Suppose that the incubation times are approximately normally distributed with a standard deviation of 2 days.
​(a) What is the probability that a randomly selected fertilized egg hatches in less than 16 ​days?
​(b) What is the probability that a randomly selected fertilized egg hatches between 18 and 20 ​days?
​(c) What is the probability that a randomly selected fertilized egg takes over 24 days to​ hatch?

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

to have more of what you want like money

step-by-step explanation:

save it by not spending on unnecessary stuff and have more

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
